Cons
Con Lack of Lua examples
Although Howl can be extended in both Lua and MoonScript, almost all bundles are written in MoonScript. This means that it is a bit harder to find examples if you'd rather write your bundle in Lua. MoonScript can be compiled to Lua but the code won't be as clean and understandable as if it would've been written in Lua by hand.
Con Proprietary
It's not free and a license costs $79.99.
Con The themes introduced in version 20 regressed certain aspects of syntax coloring
The themes simplified the syntax highlighting which lost the capacity to have as many colors as one wanted to define. Now it is limited to around 20 different colors. In general it's not a problem but in certain cases it broke coloring.
For some reason, the classic theme is the only one that is totally pleasant for readability well with syntax highlighting.
